Ontology is machine tool CNC engraving machine mechanical structure of the entity, mainly including the main moving parts, feed movement parts ( Such as the workbench, tool post) , bearing parts, Such as bed, column, etc. ) 。 In addition, CNC engraving machine and so on numerical control machine is equipped with cooling and lubrication, turned parts, the knife and measurement device and other supporting. Compared with the ordinary machine tool, CNC machine tools in the overall layout, exterior modelling, the transmission mechanism, tools, systems, and great changes have taken place in such aspects as operating mechanism, the purpose is to satisfy the requirement of numerical control technology and give full play to the characteristics of the CNC engraving machine. Sum up, including changes in the following respects: ( 1) CNC engraving machine adopts high performance main drive and the spindle assembly. Has a large transmission power, high stiffness, good vibration resistance, and the advantages of small thermal deformation. ( 2) CNC engraving machine feed drive by high drive. A short transmission chain, simple structure, high transmission precision, etc, generally adopts the ball screw pair, linear rolling guide vice, etc. ( 3) CNC engraving machine has the perfect tool automatic switching and management system. ( 4) On the machining center CNC engraving machine general workpiece automatic switching, workpiece clamping and relax. ( 5) CNC engraving machine machine itself has the very high dynamic and static stiffness. ( 6) CNC engraving machine adopts closed cover. Due to the CNC engraving machine is done automatically processing, for the operation safety, generally adopting mobile door structure of the cover, processing components of machine tool is fully closed. For a half closed loop and closed loop CNC engraving machine, also with a detection feedback device, its role is to the actual speed of the machine tool, the direction and displacement detection and processing state, the test results into electrical signal feedback to the CNC device. Detection feedback device mainly inductosyn, grating, encoders, magnetic grid and a laser range finder, etc.
